' AUTOMATTURETURN' FOR HAY-CARRIERS.

Specification of Letters Patent.

Application filed February 13, 1913.

Patented Dec. 2,1913. Serial No. 748,128.

To all whom it may concern:

Be it known that I, ANDREW BURKHOW, a citizen of the United States, residing in Huxley, county of Story, and State of Iowa,

have invented a new and useful Improve ment in Automatic Returns for Hay-Carriers, of which the following is a specification.

The object of my invention is to provide an automatic return for a hay carrier, adapted for conveying hay into a barn loft, the return being actuated by weights which are elevated by the action of the horses, engines, or other means, in conveying the hay into the barn.

My invention consists of certain details of construction hereinafter set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which- Figure I shows a skeleton view ofa barn fitted out with my device. Figs. II, III, and IV show detail views of the weights I employ; and Fig. V shows a detail view of the drum I employ. 5

Referring to the accompanying drawings the reference numeral 10 is used to indicate the frame of a barn fitted out with a track 11 and the slide of a hay carrier 12. At the rear of the barn and beneath the track 11, is an upright housing 13, provided with a door 14, the upper end of said housing being open. Mounted in said housing, transversely across its upper end, and secured for rotary movement is a drum 15, a portion of the same being of greater diameter than the balance thereof. Surrounding the larger portion of the drum is a coil spring 16 and surrounding the smaller portion of the drum is a coil spring 17, each spring being designed as a guide for the cables 18 and 19 respectively. The cable 18 is secured to the larger portion of the drum and wound around same, projecting forwardly therefrom to the forward end of the trackll, through the pulleys 20 and 21, as shown, and its other end secured to the carrier slide 12. The cable 19 is secured to the smaller portion of the drum its other end being secured to a weight 21 adapted to be moved upwardly and downwardly within the housing. Midway in the housing is a transverse bracket 22 in which is secured a horizontal roller 23. A frame provided with depending arms 25 and 26, one on each side of the roller 23, is secured for upward and downward movement in said bracket, the lower end of said arms being joined by the cross bar 27 and the upper ends of said arms providing support for a buffer 28 which is mounted thereon. The numeral 29 indicates a second weight, lighter than the weight 21, and the numeral 30 indicates a cable secured to said weight 29, projecting upwardly over the roller 23 and downwardly to a connec tion with the cross bar 27. The assembling of these parts and their construction is clearly shown in Figs. II, III and IV.

The numeral 31 indicates a cable secured to the carrier slide 12, extending rearwardly therefrom over a pulley, thence downwardly to the base of the barn through a pulley (not shown) thence forwardly through a pulley at the forward end of the barn to the outside thereof Where it is designed to be connected with any desired means for producing a pull thereon.

In practicaloperation a pull is effected on a cable 31 causing the carrier slide to move into the barn loft with its load of hay. When the hay has reached the desired point it is dropped and the pull on the cable released. When the carrier moved into the barn it obviously pulled the cable 18 which necessarily would unwind from the drum thereby rotating the same. As the drum rotated it wound the cable 19 on the smaller portion of the drum thereby raising the weight 21. 'When the weight 21 was raised from the buffer 28, the weight 29 would move downward thereby raising the frame carrying the buffer 28. When the pull on the cable 31 is removed and the cable released the weight 21 will drop, rotating the drum and winding up the cable 18 thereby moving the carrier slide over the track 11 to the forward end of the track. As the heavier weight 21 falls it strikes the buffer 28 and forces it downward to a seat on the bracket 22, the lesser weight 29 operating to reduce the shock of the larger weight in its fall.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is:

In ahay carrier a track and slide; a cable secured to said slide and extending forwardly therefrom through pulleys to a drum; a second cable secured to said drum; a weight on the end of said second cable said roller and secured to the lower end of said frame, substantially as shown and desaid Weight being mounted in a housing; a bracket 1n said housmg; a frame secured for vertical movement on said bracket; a bufier scribed. on the upper end of said frame; a roller in ANDREW BURKHOW. said bracket a Weight (smaller than the first Witnesses:

mentioned Weight) below said bracket; a
